The electronic dp Deltabar FMD72 is a differential pressure system, used to measure the pressure, level, volume or mass of liquids in pressurized tanks or distillation columns/evaporators. The high pressure sensor (HP) measures the hydrostatic pressure. The low pressure sensor (LP) measures the head pressure. The level is calculated in the transmitter using these two digital values. The electronic dp system eliminates issues of traditional differential pressure measurements.


  • Eliminates traditional mechanical issues resulting in greater process availability and reliability

  • Safety risks are minimized with the new electronic differential pressure system architecture and design

  • Lowest total cost of ownership due to reduced installation time, maintenance, downtime and spare requirements

  • Multivariable level measurement: HART-based differential pressure, head pressure and sensor temperatures from one system

  • Continuous health indication of the entire system via HART-based diagnostic

  • High reproducibility and long-term stability

  • Process safety assured with small flush mounted process connections in hygienic applications


For differential pressure, level, volume or mass measurement of liquids in pressurized tanks and distillation columns/evaporators.

  • Process connections: Threads, flanges and hygienic connections

  • Process temperature: -40 to +125°C (-40 to +257°F), optional 250°C (480°F)
